Nicholson will play Helen Torrance, described as “a former big-city homicide detective who left her harrowing career to become a small-town sheriff and loving wife. However, when a gruesome crime occurs, she’s thrust back into the traumas of her past – just as she’s begun her hardest case yet: fostering a teenage boy.”

Meanwhile, Tyler Young (Empire) has landed the series-regular role of that “sensitive yet tough” foster child, Philip O’Brien. As he settles into his new and idyllic small-town life, Philip begins to fall in love with his classmate Lukas. When the boys witness a quadruple homicide, however, “Philip becomes more troubled than ever, as the two boys swear themselves to secrecy for fear of being outed.”
